The frame and the shoji are connected by a connecting arm provided with a cam groove, and a contact attached to the tip of the lever part of the switchgear is inserted into the cam groove of the switch arm, and the lever part is shaken by the operating force of the switchgear. The one that opens and closes the shoji by swinging the connecting arm by movement (see, for example, Patent Document 1), the tip of the folding arm that is driven by the opening and closing device and the shoji are connected, and the operating force of the opening and closing device Swings (expands and retracts) the operating arm to open and close the shoji (see, for example, Patent Document 2), and the rotational movement of the linkage arm portion by the operating force of the opening and closing device follows the guide plate via the interlocking plate. Up and down The base plate fixed to the vertical frame is provided with a second slide hole and a base plate pin, and the second arm pin provided at the frame side end of the connecting arm is a second slide. Inserted into the hole and fixed to the actuating plate so as to be rotatable, the base plate pin is inserted into the third slide hole provided at the frame side end of the connecting arm, and the connecting arm is rotated by the sliding movement of the actuating plate. There are those that open and close the shoji (see, for example, Patent Document 3).

これらの開口部装置は、開閉装置により障子を閉じる際に施錠状態となり、開閉装置により障子を開く際に解錠状態となるロック機構を備えており、ロック機構の操作を行う機構を開閉装置と別に設ける必要がないため、明り取り及び換気用等、特に高所での使用に適している。
例えば、特許文献1の開口部装置は、連結アームのカム溝の上部に折曲部の切り込みを設け、該切り込みを底部の第一経路と、上部の係止点を備えた第二経路によって構成し、障子の閉鎖時に、開閉ユニット(オペレータ)により回動するレバー部先端の接触子を係止点に保持するロック機構を備えている。
また、特許文献2の開口部装置は、作動アームの先端と障子との連結部に、障子の閉鎖時又は閉鎖位置の手前で作動アームの先端の障子開閉方向と略直交する方向への移動を許容する移動許容部を設け、障子の閉鎖時に、作動アームの先端側に設けた係合部を枠体に設けた係合受部に係合させるロック機構を備えている。

These opening devices are provided with a lock mechanism that is locked when the shoji is closed by the opening and closing device and unlocked when the shoji is opened by the opening and closing device, and the mechanism for operating the lock mechanism is referred to as an opening and closing device. Since it does not need to be provided separately, it is suitable for use in high places, such as for lighting and ventilation.
For example, the opening device of Patent Document 1 is provided with an incision in a bent portion in the upper part of a cam groove of a connecting arm, and the incision is configured by a first path at the bottom and a second path having a locking point at the top. And the locking mechanism which hold | maintains the contactor of the lever part tip rotated by an opening / closing unit (operator) at a latching point at the time of closing of a shoji.
Moreover, the opening part apparatus of patent document 2 moves to the connection part of the front-end | tip of a working arm and a shoji in the direction substantially orthogonal to the shoji opening-and-closing direction of the front-end | tip of a working arm at the time of a close of a shoji or before a closed position. A permissible movement allowing portion is provided, and a locking mechanism is provided for engaging an engaging portion provided on the distal end side of the operating arm with an engaging receiving portion provided on the frame when the shoji is closed.

特開2005−36398号公報(図1−5)Japanese Patent Laying-Open No. 2005-36398 (FIG. 1-5) 特開2003−184402号公報(図1−4)JP 2003-184402 A (FIGS. 1-4) 特開2007−100444号公報(図1−6)Japanese Unexamined Patent Publication No. 2007-1000044 (FIG. 1-6)

特許文献1のロック機構では連結アームのカム溝(長孔)にレバー部先端の接触子(ピン)が引っ掛かっているだけであるため、また特許文献2のロック機構では係合受部のテーパ(傾斜)部に係合部(ピン)が当たっているだけであるため、風圧の変動や外部からの揺動の繰り返しによってガタツキが生じたり、ロック機構が外れて解錠状態となるおそれがあるとともに、ロック機構の信頼性を長期にわたって保持することは困難である。
よって、特許文献1及び特許文献2のような従来の開口部装置では、開閉装置の操作によりロック機構も操作することができるという特徴がある反面、耐風圧性能及び防犯性能については十分な性能が得られておらず、これらの性能向上の観点からは改良の余地がある。
In the lock mechanism of Patent Document 1, only the contact (pin) at the tip of the lever is caught in the cam groove (long hole) of the connecting arm. In the lock mechanism of Patent Document 2, the taper ( Since only the engaging part (pin) is in contact with the (inclined) part, there is a risk that rattling may occur due to wind pressure fluctuations or repeated external swinging, or the lock mechanism may come off and become unlocked. It is difficult to maintain the reliability of the lock mechanism for a long time.
Therefore, the conventional opening devices such as Patent Document 1 and Patent Document 2 have a feature that the lock mechanism can be operated by operating the opening / closing device, but have sufficient performance against wind pressure resistance and crime prevention performance. It has not been obtained, and there is room for improvement from the viewpoint of improving these performances.

また、特許文献3のロック機構は、前記のとおり、連結アームの枠側端部に設けた第2アームピンをベース板の第2スライド孔に挿通して作動板に回動自在に固定し、連結アームの枠側端部に設けた第3スライド孔内にベース板ピンを挿通させることにより、作動板のスライド動作により連結アームを回動させて障子を開閉する構成であるため、連結アームの第2アームピン及びベース板の第2スライド孔の間並びに連結アームの第3スライド孔及びベース板ピンの間でガタツキが生じやすく、したがって、このようなガタツキ防止のために、連結アーム部ロック機構を備える必要がある。
その上、このような連結アーム部ロック機構のみでは、風圧の変動や外部からの揺動の繰り返しによってガタツキが生じたり、ロック機構が外れて解錠状態となるおそれがあるとともに、ロック機構の信頼性を長期にわたって保持することは困難であるため、耐風圧性能及び防犯性能の向上のために、さらに作動板部ロック機構を備える必要がある。
よって、特許文献3のような従来の開口部装置では、開閉装置の操作によりロック機構も操作することができるという特徴がある反面、障子の開閉機構及びロック機構の構成が複雑であり、部品点数が多いこと及び組み付け調整作業に時間がかかることからコストが増大する。
さらに、連結アームに切欠が形成されていることから連結アームが変形しやすいこと及び構成が複雑であること等から、障子の開閉機構及びロック機構の動作の信頼性が長期間の使用により低下する場合がある。
In addition, as described above, the lock mechanism of Patent Document 3 is configured so that the second arm pin provided at the frame side end of the connecting arm is inserted into the second slide hole of the base plate and is rotatably fixed to the operating plate. Since the base plate pin is inserted into the third slide hole provided at the frame side end of the arm, the connecting arm is rotated by the sliding movement of the operating plate to open and close the shoji. A backlash is likely to occur between the two arm pins and the second slide hole of the base plate and between the third slide hole of the connection arm and the base plate pin. Therefore, in order to prevent such backlash, a connection arm portion locking mechanism is provided. There is a need.
In addition, with such a connecting arm portion locking mechanism alone, there is a risk that rattling may occur due to wind pressure fluctuations or repeated external swinging, or the locking mechanism may come off and become unlocked, and the reliability of the locking mechanism Since it is difficult to maintain the property over a long period of time, it is necessary to further include an operating plate lock mechanism in order to improve the wind pressure resistance performance and the crime prevention performance.
Therefore, the conventional opening device as disclosed in Patent Document 3 is characterized in that the lock mechanism can be operated by operating the opening / closing device, but the configuration of the opening / closing mechanism and locking mechanism of the shoji is complicated, and the number of parts is reduced. The cost increases due to the large amount of time and assembly adjustment work.
Furthermore, since the connecting arm is formed with a notch, the connecting arm is easily deformed and the structure is complicated. Therefore, the reliability of the operation of the shoji opening / closing mechanism and the locking mechanism is lowered by long-term use. There is a case.

そこで本発明が前述の状況に鑑み、解決しようとするところは、開閉装置の操作によりロック機構も操作することができる構成でありながら、より実用的な簡素な構成により耐風圧性能及び防犯性能を向上することができ、障子の開閉機構及びロック機構の信頼性を長期にわたって保持することがきる開口部装置を提供する点にある。   Therefore, in view of the above-described situation, the present invention intends to solve the problem that wind pressure resistance performance and crime prevention performance can be achieved by a more practical simple configuration while the lock mechanism can be operated by operating the switchgear. It is an object to provide an opening device that can be improved and can maintain the reliability of the opening / closing mechanism and the locking mechanism of the shoji for a long period of time.

本発明に係る開口部装置は、前記課題解決のために、室内側から操作する開閉装置により、左右の縦枠と上下の横枠とからなる枠体内に納められた障子を室内外方向へ開閉することができる開口部装置であって、一端が前記縦枠又は横枠に対して水平支軸又は垂直支軸まわりに揺動可能に支持され、他端が前記障子の戸先框に対して垂直方向又は水平方向にスライド可能に連結された開閉アームと、前記開閉装置の操作力により前記支軸と平行な揺動中心軸まわりに揺動する操作アームと、前記戸先框に対向する前記縦枠又は横枠に沿って取り付けられたガイド部材により支持され、該ガイド部材に沿って垂直方向又は水平方向にスライド可能なスライド体と、該スライド体に対して一端が水平支軸又は垂直支軸まわりに揺動可能に連結された連動アームと、該連動アームの他端と前記操作アームの先端とを水平支軸又は垂直支軸まわりに揺動可能に連結する連結軸と、前記戸先框及び前記スライド体に設けられた一対の掛止部材とを備え、前記開閉アームの中間部分に、前記連結軸が内挿されて相対移動するように長手方向に延びる略直線状の開閉操作用長孔と、前記障子が閉じた状態でさらに前記連結軸が室内側へ相対移動するように、該開閉操作用長孔に繋がり室内側へ屈曲する略円弧状のロック操作用長孔を形成してなり、前記開閉装置の操作力による前記操作アームの揺動に伴い、前記連結軸が前記開閉操作用長孔に沿って移動することにより前記開閉アームが揺動して前記障子が開閉し、前記障子が閉じた状態で前記連結軸が前記ロック操作用長孔に沿って室内側へ移動することにより前記連結アームが揺動して前記スライド体がスライドし、前記一対の掛止部材が掛止して施錠状態となり、この施錠状態で前記連結軸が前記ロック操作用長孔に沿って室外側へ移動することにより前記施錠状態が解除されて解錠状態となるものである。   In order to solve the above problems, an opening device according to the present invention opens and closes a shoji housed in a frame composed of left and right vertical frames and upper and lower horizontal frames in an indoor / outdoor direction by an open / close device operated from the indoor side. An opening device that is capable of swinging around a horizontal support shaft or a vertical support shaft with respect to the vertical frame or the horizontal frame, and having the other end supported with respect to the door toe of the shoji An open / close arm that is slidably connected in a vertical direction or a horizontal direction, an operation arm that swings around a swing center axis that is parallel to the support shaft by an operation force of the open / close device, and the door that faces the door rod A slide body supported by a guide member attached along the vertical frame or the horizontal frame and slidable in the vertical direction or the horizontal direction along the guide member, and one end of the slide body with respect to the horizontal support shaft or the vertical support. It is connected so that it can swing around the shaft. An interlock arm, a connecting shaft that connects the other end of the interlock arm and the tip of the operation arm so as to be swingable around a horizontal support shaft or a vertical support shaft, and a pair provided on the door toe and the slide body A substantially linear opening / closing operation elongated hole extending in the longitudinal direction so that the connecting shaft is inserted and moved relative to the intermediate portion of the opening / closing arm, and the shoji is closed In addition, a substantially arc-shaped locking operation long hole that is connected to the opening / closing operation long hole and is bent toward the indoor side is formed so that the connecting shaft moves relative to the indoor side. As the operating arm swings, the connecting shaft moves along the opening / closing operation slot so that the opening / closing arm swings to open and close the shoji, and the shoji is closed. Moves to the indoor side along the slot for locking operation. By doing so, the connecting arm swings and the slide body slides, and the pair of hooking members hooks into a locked state. In this locked state, the connecting shaft moves along the lock operation slot. By moving to the outdoor side, the locked state is released and the unlocked state is obtained.

本発明に係る開口部装置によれば、室内側から操作する開閉装置により、左右の縦枠と上下の横枠とからなる枠体内に納められた障子を室内外方向へ開閉することができる開口部装置であって、一端が前記縦枠又は横枠に対して水平支軸又は垂直支軸まわりに揺動可能に支持され、他端が前記障子の戸先框に対して垂直方向又は水平方向にスライド可能に連結された開閉アームと、前記開閉装置の操作力により前記支軸と平行な揺動中心軸まわりに揺動する操作アームと、前記戸先框に対向する前記縦枠又は横枠に沿って取り付けられたガイド部材により支持され、該ガイド部材に沿って垂直方向又は水平方向にスライド可能なスライド体と、該スライド体に対して一端が水平支軸又は垂直支軸まわりに揺動可能に連結された連動アームと、該連動アームの他端と前記操作アームの先端とを水平支軸又は垂直支軸まわりに揺動可能に連結する連結軸と、前記戸先框及び前記スライド体に設けられた一対の掛止部材とを備え、前記開閉アームの中間部分に、前記連結軸が内挿されて相対移動するように長手方向に延びる略直線状の開閉操作用長孔と、前記障子が閉じた状態でさらに前記連結軸が室内側へ相対移動するように、該開閉操作用長孔に繋がり室内側へ屈曲する略円弧状のロック操作用長孔を形成してなり、前記開閉装置の操作力による前記操作アームの揺動に伴い、前記連結軸が前記開閉操作用長孔に沿って移動することにより前記開閉アームが揺動して前記障子が開閉し、前記障子が閉じた状態で前記連結軸が前記ロック操作用長孔に沿って室内側へ移動することにより前記連結アームが揺動して前記スライド体がスライドし、前記一対の掛止部材が掛止して施錠状態となり、この施錠状態で前記連結軸が前記ロック操作用長孔に沿って室外側へ移動することにより前記施錠状態が解除されて解錠状態となるので、開閉装置(オペレータ)の操作力による操作アームの揺動により開閉アームが直接駆動されて障子を開閉する操作が行われるとともに、操作アームの揺動に伴って、操作アームの先端に枢結された連動アームが揺動し、連動アームの他端に枢結されたスライド体がガイド部材に沿ってスライドすることにより施錠・解錠の操作が行われるため、開閉装置の操作によりロック機構も操作することができる。したがって、ロック機構の操作を行う機構を開閉装置と別に設ける必要がないため、明り取り及び換気用等、特に高所での使用に適している。   According to the opening device according to the present invention, the opening / closing device operated from the indoor side can open and close the shoji housed in the frame composed of the left and right vertical frames and the upper and lower horizontal frames in the indoor and outdoor directions. One end of which is supported so as to be swingable around a horizontal support shaft or a vertical support shaft with respect to the vertical or horizontal frame, and the other end is vertical or horizontal with respect to the door toe of the shoji. An open / close arm slidably connected to the open / close arm, an operating arm that swings around a swinging central axis parallel to the support shaft by an operating force of the open / close device, and the vertical frame or horizontal frame that faces the door rod Is supported by a guide member attached along the guide member, and is slidable vertically or horizontally along the guide member, and one end of the slide member swings around a horizontal support shaft or a vertical support shaft. An interlocking arm connected as possible, A connecting shaft that connects the other end of the interlocking arm and the tip of the operation arm so as to be swingable around a horizontal support shaft or a vertical support shaft, and a pair of latch members provided on the door toe and the slide body; A substantially linear opening / closing operation elongated hole extending in the longitudinal direction so that the connecting shaft is inserted and moved relative to the intermediate portion of the opening / closing arm, and the connecting shaft is further closed when the shoji is closed. Is formed with a substantially arc-shaped locking operation long hole that is connected to the opening / closing operation long hole and bent toward the indoor side so as to move relatively to the indoor side. With the movement, the connecting shaft moves along the long opening / closing operation hole, so that the opening / closing arm swings to open / close the shoji, and in a state where the shoji is closed, the connecting shaft is used for the locking operation. By moving indoors along the long hole The connecting arm swings and the slide body slides, and the pair of locking members are locked to be in a locked state. In this locked state, the connecting shaft moves to the outdoor side along the long slot for locking operation. By moving, the locked state is released and the unlocked state is entered, so that the opening and closing arm is directly driven by the swinging of the operating arm by the operating force of the opening and closing device (operator), and the operation to open and close the shoji is performed. As the operating arm swings, the interlocking arm pivoted to the tip of the operating arm swings, and the slide body pivoted to the other end of the interlocking arm slides along the guide member to lock and unlock. Since the lock is operated, the lock mechanism can also be operated by operating the opening / closing device. Therefore, since it is not necessary to provide a mechanism for operating the lock mechanism separately from the opening / closing device, it is suitable for use in high places, such as for lighting and ventilation.

また、開閉アームの開閉操作用長孔内を操作アーム先端の連結軸がスライドするため、開閉アームと操作アームとにより揺動スライダクランク機構が構成され、操作アーム及び連動アームの揺動によりスライド体がスライドするため、ガイド部材及びスライド体並びに操作アーム及び連動アームにより往復スライダクランク機構が構成され、これらのスライダクランク機構は、簡素な構成で作動誤差が少なく、強度及び剛性を高めることが容易であり、安定かつ確実に動作するものである。
よって、操作アームにより駆動される開閉機構が前記揺動スライダクランク機構により構成され、同じく操作アームにより駆動されて一対の掛止部材を掛止させるロック機構が前記往復スライダクランク機構により構成されることから、開閉機構及びロック機構の動作が安定かつ確実なものとなるとともに、その信頼性を長期にわたって保持することができる。
その上、障子が閉じた状態でさらに連結軸をロック操作用長孔に沿って室内側へ移動させることにより、前記往復スライダクランク機構を操作して一対の掛止部材を掛止させることにより施錠状態となることから、ロック機構の動作がさらに確実なものとなるとともに、一対の掛止部材により障子が閉じた状態でさらに開口部装置の枠体と障子とを引き付けて密閉度を向上することができる。
その上さらに、前記揺動スライダクランク機構を用いた開閉機構及び前記往復スライダクランク機構と一対の掛止部材とを組み合わせたロック機構の構造上、上記密閉度の向上とともに、風圧の変動や外部からの揺動の繰り返しによってもガタツキが生じたり、ロック機構が外れて解錠状態となるおそれがないことから、十分な耐風圧性能及び防犯性能を得ることができる。
Further, since the connecting shaft at the tip of the operation arm slides in the opening / closing operation long hole of the opening / closing arm, the opening / closing arm and the operation arm constitute a swing slider crank mechanism, and the slide body is formed by the swing of the operation arm and the interlocking arm. Therefore, the reciprocating slider crank mechanism is configured by the guide member, the slide body, the operation arm, and the interlocking arm. These slider crank mechanisms have a simple configuration with little operation error, and can easily increase strength and rigidity. Yes, it operates stably and reliably.
Therefore, the opening / closing mechanism driven by the operating arm is configured by the swing slider crank mechanism, and the locking mechanism that is also driven by the operating arm and latches the pair of locking members is configured by the reciprocating slider crank mechanism. Therefore, the operation of the opening / closing mechanism and the lock mechanism can be stable and reliable, and the reliability thereof can be maintained for a long time.
In addition, when the shoji is closed, the connecting shaft is further moved to the indoor side along the lock operation long hole to operate the reciprocating slider crank mechanism to lock the pair of hook members. Therefore, the lock mechanism can be operated more reliably, and the pair of hook members can further attract the frame and the shoji of the opening device while the shoji is closed to improve the sealing degree. Can do.
Furthermore, due to the structure of the opening / closing mechanism using the swing slider crank mechanism and the lock mechanism combining the reciprocating slider crank mechanism and a pair of latch members, the sealing degree is improved and the fluctuation of the wind pressure or from the outside Since there is no possibility of rattling or the unlocking mechanism coming off due to repeated swinging, it is possible to obtain sufficient wind pressure resistance and crime prevention performance.

As shown in FIG. 1, the frame 3 is composed of an upper frame 3U and a lower frame 3L which are horizontal frames, and left and right vertical frames 3S and 3S, and the shoji 4 is an upper frame 4U and a lower frame 4L which are horizontal frames and left and right vertical frames. The upper and lower stays 5 are composed of the collars 4S, 4S and the two front and rear glasses 4G, 4G, etc., and are respectively attached between the upper frame 3U and the upper collar 4U and between the lower frame 3L and the lower collar 4L. The shoji 4 is supported by the frame 3 by 5.

また、開閉装置2は、障子4の開閉端である戸先框4Tに対向する縦枠3Sに固定され、モータ2B(図2参照。)により入力軸である回転軸2Aを駆動することにより(例えば図1の矢印A参照。)、あるいは、チェーン2Cを操作することによりスプロケット2D(図3参照。)を回転させて回転軸2Aを駆動することにより(例えば図1の矢印A参照。)、回転軸2Aと同軸に固定された図示しないウォームに噛み合うウォームホイール7C(図4参照。)を前記ウォームに対して相対的に移動させ、水平の揺動中心軸7Aまわりに操作アーム7を揺動させるものである。   Further, the opening / closing device 2 is fixed to a vertical frame 3S facing the door toe 4T that is an opening / closing end of the shoji 4, and is driven by a motor 2B (see FIG. 2) to drive a rotary shaft 2A that is an input shaft ( For example, refer to arrow A in FIG. 1), or by rotating the sprocket 2D (see FIG. 3) by operating the chain 2C to drive the rotating shaft 2A (see, for example, arrow A in FIG. 1). A worm wheel 7C (see FIG. 4) that meshes with a worm (not shown) fixed coaxially with the rotary shaft 2A is moved relative to the worm, and the operation arm 7 is swung around a horizontal swing center shaft 7A. It is something to be made.

図1〜図4に示すように、水平支軸である段付きピン19の軸部を開閉アーム6の一端(枠側端部)の通孔6A及び戸先框4Tに対向する縦枠3Sに取り付けられた枠側ブラケット17の通孔17Aを通して軸端をかしめることにより、開閉アーム6の一端は、縦枠3Sに対して段付きピン19まわりに揺動可能に支持される。
また、開閉アーム6の他端(框側端部)の水平ピン16が、障子4の戸先框4Tに取り付けられた障子側ブラケット18の上下に延びる長孔18Aに内挿されるため、開閉アーム6の他端は、障子4の戸先框4Tに対して垂直方向(上下方向)にスライド可能に連結される。
そして、開閉アーム6には、その中間部分に、長手方向に延びる略直線状の開閉操作用長孔14及び開閉操作用長孔14に繋がり室内側へ屈曲する略円弧状のロック操作用長孔15が形成されている。
As shown in FIGS. 1 to 4, the shaft portion of the stepped pin 19, which is a horizontal support shaft, is connected to the vertical frame 3 </ b> S facing the through hole 6 </ b> A at one end (frame side end portion) of the opening / closing arm 6 and the door-end rod 4 </ b> T. By caulking the shaft end through the through hole 17A of the attached frame side bracket 17, one end of the open / close arm 6 is supported so as to be swingable around the stepped pin 19 with respect to the vertical frame 3S.
Further, since the horizontal pin 16 at the other end (edge side end) of the opening / closing arm 6 is inserted into a long hole 18 </ b> A extending up and down of the shoji side bracket 18 attached to the door toe 4 </ b> T of the shoji 4, the opening / closing arm The other end of 6 is connected to the door toe 4T of the shoji 4 so as to be slidable in the vertical direction (vertical direction).
The opening / closing arm 6 has a substantially linear opening / closing operation elongated hole 14 extending in the longitudinal direction and a substantially arc-shaped locking operation elongated hole bent inward in the room connected to the opening / closing operation elongated hole 14 at an intermediate portion thereof. 15 is formed.

さらに、戸先框4Tに対向する縦枠3Sに沿ってガイド部材8が取り付けられ、ガイド部材8によりスライド体9が垂直方向にスライド可能に支持される。
そして、水平支軸である段付きピン20の軸部をスライド体9の下端部の通孔9A及び連動アーム10の一端(枠側端部)の通孔10Aを通して軸端をかしめることにより、連動アーム10の一端はスライド体9に対して段付きピン20まわりに揺動可能に連結される。
Further, a guide member 8 is attached along the vertical frame 3S facing the door toe 4T, and the slide body 9 is supported by the guide member 8 so as to be slidable in the vertical direction.
Then, the shaft end of the stepped pin 20 which is a horizontal support shaft is caulked at the shaft end through the through hole 9A at the lower end portion of the slide body 9 and the through hole 10A at one end (frame side end portion) of the interlocking arm 10. One end of the interlocking arm 10 is connected to the slide body 9 so as to be swingable around the stepped pin 20.

さらにまた、連動アーム10の他端(遊端部)には連結軸である水平ピン11が垂設されており、水平ピン11が操作アーム7先端部の通孔7B内に挿入されるため、連動アーム10の他端(遊端部)と操作アーム7の先端とは、水平ピン11まわりに揺動可能に連結される。
また、水平ピン11はさらに開閉アーム6の開閉操作用長孔14内にも挿入され、水平ピン11の側面11Aが開閉操作用長孔14を形成する側壁に摺接した状態で、取付けねじ21が水平ピン11の螺孔に螺合される。このようにして開閉アーム6の開閉操作用長孔14に沿って相対移動可能な水平ピン11は、障子4が閉じた状態(図5参照。)で、その側面11Aをロック操作用長孔15を形成する側壁に摺接させながら、さらに室内側へ相対移動することができる。
さらに、障子4の戸先框4Tには掛止ピン12が取り付けられ、縦枠3Sに対して垂直方向にスライドするスライド体9には鈎状掛止片13が取り付けられ、これら掛止ピン12及び鈎状掛止片13が一対の掛止部材を構成する。
Furthermore, a horizontal pin 11 as a connecting shaft is suspended from the other end (free end portion) of the interlocking arm 10, and the horizontal pin 11 is inserted into the through hole 7B at the distal end of the operation arm 7, The other end (free end portion) of the interlocking arm 10 and the tip of the operation arm 7 are coupled to be swingable around the horizontal pin 11.
The horizontal pin 11 is also inserted into the opening / closing operation long hole 14 of the opening / closing arm 6, and the mounting screw 21 is in a state where the side surface 11 A of the horizontal pin 11 is in sliding contact with the side wall forming the opening / closing operation long hole 14. Is screwed into the screw hole of the horizontal pin 11. In this way, the horizontal pin 11 that can be relatively moved along the opening / closing operation slot 14 of the opening / closing arm 6 has the side surface 11A of the locking operation slot 15 in the state in which the shoji 4 is closed (see FIG. 5). Can be further moved relative to the indoor side while being in sliding contact with the side wall.
Further, a latch pin 12 is attached to the door end fence 4T of the shoji 4, and a hook-like latch piece 13 is attached to the slide body 9 that slides in the vertical direction with respect to the vertical frame 3S. And the hook-shaped latching piece 13 comprises a pair of latching member.

以上のような構成により、開閉装置2の入力軸2Aを例えば図1の矢印A方向に回転させることにより、操作アーム7が揺動中心軸7Aまわりに揺動して水平ピン11が開閉操作用長孔14に沿って移動するため、例えば図1の矢印Bのように開閉アーム6を揺動させて障子4を閉じることができ(図5の障子4を閉じた状態参照。)、この状態からさらに開閉装置2の入力軸2Aを同方向に回転させることにより、開閉アーム6は揺動せずに操作アーム7が室内側へ揺動して水平ピン11がロック操作用長孔15に沿って室内側へ移動するため、連動アーム10を介してスライド体9とともに鈎状掛止片13が上昇し(図5の矢印C参照。)、鈎状掛止片13が掛止ピン12に掛止する(図6の施錠状態参照。)。   With the configuration as described above, by rotating the input shaft 2A of the opening / closing device 2 in the direction of arrow A in FIG. 1, for example, the operating arm 7 swings around the swing center shaft 7A, and the horizontal pin 11 opens and closes. Since it moves along the long hole 14, the shoji 4 can be closed by swinging the open / close arm 6 as shown by an arrow B in FIG. 1 (see the state in which the shoji 4 is closed in FIG. 5). When the input shaft 2A of the opening / closing device 2 is further rotated in the same direction, the opening / closing arm 6 does not swing but the operating arm 7 swings indoors, and the horizontal pin 11 extends along the lock operating slot 15. Therefore, the hook-shaped hooking piece 13 rises together with the slide body 9 via the interlocking arm 10 (see arrow C in FIG. 5), and the hook-shaped hooking piece 13 is hooked on the hooking pin 12. Stop (see the locked state in FIG. 6).

また、この施錠状態から、開閉装置2の入力軸2Aを図1及び図5の矢印Aと逆方向に回転させることにより、操作アーム7が室外側へ揺動して水平ピン11がロック操作用長孔15に沿って室外側へ移動するため、連動アーム10を介してスライド体9とともに鈎状掛止片13が下降し、鈎状掛止片13が掛止ピン12から外れて解錠状態となり、この状態からさらに開閉装置2の入力軸2Aを同方向に回転させることにより、操作アーム7の揺動に伴って水平ピン11が開閉操作用長孔14に沿って移動するため、開閉アーム6を図1の矢印Bと逆方向に揺動させて障子4を開くことができる。   Further, from this locked state, by rotating the input shaft 2A of the opening / closing device 2 in the direction opposite to the arrow A in FIGS. 1 and 5, the operating arm 7 swings to the outdoor side and the horizontal pin 11 is used for locking operation. In order to move to the outdoor side along the long hole 15, the hook-like hooking piece 13 is lowered together with the slide body 9 via the interlocking arm 10, and the hook-like hooking piece 13 is released from the hooking pin 12 and is unlocked. From this state, by further rotating the input shaft 2A of the opening / closing device 2 in the same direction, the horizontal pin 11 moves along the opening / closing operation long hole 14 as the operation arm 7 swings. The shoji 4 can be opened by swinging 6 in the direction opposite to the arrow B in FIG.

このように、開閉装置2の操作力による操作アーム7の揺動により開閉アーム6が直接駆動されて障子4を開閉する操作が行われるとともに、操作アーム7の揺動に伴って、操作アーム7の先端に枢結された連動アーム10が揺動し、連動アーム10の他端に枢結されたスライド体9がガイド部材8に沿ってスライドすることにより施錠・解錠の操作が行われるため、開閉装置2の操作によりロック機構も操作することができる。したがって、ロック機構の操作を行う機構を開閉装置と別に設ける必要がないため、明り取り及び換気用等、特に高所での使用に適している。   As described above, the opening / closing arm 6 is directly driven by the swing of the operation arm 7 by the operating force of the opening / closing device 2 to perform the opening / closing operation of the shoji 4, and the operation arm 7 is moved along with the swing of the operation arm 7. Since the interlocking arm 10 pivoted to the tip of the arm swings and the slide body 9 pivoted to the other end of the interlocking arm 10 slides along the guide member 8, the locking / unlocking operation is performed. The lock mechanism can also be operated by operating the opening / closing device 2. Therefore, since it is not necessary to provide a mechanism for operating the lock mechanism separately from the opening / closing device, it is suitable for use in high places, such as for lighting and ventilation.

また、開閉アーム6の開閉操作用長孔14内を操作アーム7先端の水平ピン11がスライドするため、開閉アーム6と操作アーム7とにより揺動スライダクランク機構が構成され、操作アーム7及び連動アーム10の揺動によりスライド体9がスライドするため、ガイド部材8及びスライド体9並びに操作アーム7及び連動アーム10により往復スライダクランク機構が構成され、これらのスライダクランク機構は、簡素な構成で作動誤差が少なく、強度及び剛性を高めることが容易であり、安定かつ確実に動作するものである。
よって、操作アーム7により駆動される開閉機構が前記揺動スライダクランク機構により構成され、同じく操作アーム7により駆動されて一対の掛止部材12,13を掛止させるロック機構が前記往復スライダクランク機構により構成されることから、開閉機構及びロック機構の動作が安定かつ確実なものとなるとともに、その信頼性を長期にわたって保持することがきる。
Further, since the horizontal pin 11 at the tip of the operation arm 7 slides inside the opening / closing operation long hole 14 of the opening / closing arm 6, the opening / closing arm 6 and the operation arm 7 constitute a swing slider crank mechanism. Since the slide body 9 slides by swinging the arm 10, the reciprocating slider crank mechanism is configured by the guide member 8, the slide body 9, the operation arm 7, and the interlocking arm 10, and these slider crank mechanisms operate with a simple configuration. There are few errors, it is easy to increase strength and rigidity, and it operates stably and reliably.
Therefore, the opening / closing mechanism driven by the operation arm 7 is constituted by the swing slider crank mechanism, and the lock mechanism which is also driven by the operation arm 7 to latch the pair of latch members 12 and 13 is the reciprocating slider crank mechanism. Therefore, the operations of the opening / closing mechanism and the locking mechanism are stable and reliable, and the reliability can be maintained for a long time.

その上、障子4が閉じた状態でさらに水平ピン11をロック操作用長孔15に沿って室内側へ移動させることにより、前記往復スライダクランク機構を操作して一対の掛止部材12,13を掛止させることにより施錠状態となることから、ロック機構の動作がさらに確実なものとなるとともに、障子4が閉じた状態で、一対の掛止部材12,13によりさらに開口部装置1の枠体3と障子4とを引き付けて密閉度を向上することができる。
その上さらに、前記揺動スライダクランク機構を用いた開閉機構及び前記往復スライダクランク機構と一対の掛止部材12,13とを組み合わせたロック機構の構造上、例えば図6の施錠状態において、上記密閉度の向上とともに、風圧の変動や外部からの揺動の繰り返しによっても開口部装置1にガタツキが生じたり、ロック機構が外れて解錠状態となるおそれがないことから、十分な耐風圧性能及び防犯性能を得ることができる。
In addition, when the shoji 4 is closed, the horizontal pin 11 is further moved indoors along the lock operation slot 15 to operate the reciprocating slider crank mechanism so that the pair of latch members 12 and 13 are moved. Since the locked state is obtained by the hooking, the operation of the lock mechanism is further ensured, and the frame of the opening device 1 is further closed by the pair of hooking members 12 and 13 with the shoji 4 closed. 3 and the shoji 4 can be attracted and the sealing degree can be improved.
Furthermore, due to the structure of the opening / closing mechanism using the swing slider crank mechanism and the lock mechanism combining the reciprocating slider crank mechanism and the pair of latch members 12 and 13, for example, in the locked state of FIG. Since there is no possibility that the opening device 1 will be rattled due to wind pressure fluctuations or repeated swinging from the outside, or the lock mechanism may come off and enter the unlocked state. Security performance can be obtained.

以上の説明においては、一対の掛止部材を、戸先框4Tに取り付けた掛止ピン12とスライド体9に取り付けた鈎状掛止片13とにより構成する場合について説明したが、例えば戸先框4Tに鈎状掛止片を取り付けてスライド体9に掛止ピンを取り付けてもよく、障子4が閉じた状態で開閉装置2により前記往復スライダクランク機構を操作することにより、一対の掛止部材が掛止して施錠状態となる構成であればよい。
また、以上の説明においては、開口部装置1が縦すべり出し窓である場合について説明したが、開口部装置1は、横すべりだし窓、開き窓又は突き出し窓等であってもよく、開口部装置1が例えば横すべりだし窓である場合には、開閉アーム6が水平方向に揺動するように、その枠側端部を枠体3の横枠(上枠3U又は下枠3L)に対して垂直支軸まわりに揺動可能に連結し、その框側端部を障子4の戸先框に対して水平方向にスライド可能に連結し、前記戸先框に対向する横枠に沿ってガイド部材8を取り付け、ガイド部材8に沿ってスライド体9を水平方向にスライド可能とし、操作アーム7及び連動アーム10を垂直支軸まわりに揺動可能なものとすればよい。
In the above description, the case where the pair of latching members is constituted by the latching pin 12 attached to the door toe cage 4T and the hook-like latching piece 13 attached to the slide body 9 has been described. A hook-like hooking piece may be attached to the hook 4T and a hooking pin may be attached to the slide body 9. A pair of hooks can be obtained by operating the reciprocating slider crank mechanism with the opening / closing device 2 with the shoji 4 closed. What is necessary is just a structure which a member latches and becomes a locked state.
In the above description, the case where the opening device 1 is a vertical sliding window has been described. However, the opening device 1 may be a horizontal sliding window, an opening window, a protruding window, or the like. Is a side sliding window, for example, the frame side end is vertically supported with respect to the horizontal frame (upper frame 3U or lower frame 3L) of the frame 3 so that the open / close arm 6 swings in the horizontal direction. It is connected so as to be swingable around the shaft, and the end of the heel side is connected slidably in the horizontal direction with respect to the door toe of the shoji 4, and the guide member 8 is provided along the horizontal frame facing the door toe. The slide body 9 can be slid in the horizontal direction along the attachment and guide member 8, and the operation arm 7 and the interlocking arm 10 can be swung around the vertical support shaft.
